Digital design & operations: creating new value and competitive advantage

PSE's gPROMS advanced process modelling software and services for digital design and intelligent digital operation are transforming the way the chemical process industries design and operate plants.

gPROMS ProcessBuilder's combination of high-fidelity reactor and separation models coupled with advanced global system analysis (GSA) and industry-leading optimisation techniques make it possible to dramatically accelerate next-generation process design and identify millions of dollars from 'already-optimised' processes.

Our laboratory-to-operating-plant approach reduces time-to-market and risk for new process development, and helps minimise capital and operating cost.

The downstream value chain

PSE's capabilities cover the entire downstream process application space with a single steady-state and dynamic process modelling environment, gPROMS ProcessBuilder.


ProcessBuilder’s Olefins model library allows easy high-fidelity offline modelling of ethylene plants with different furnace types for whole-plant optimisation and what-if studies. The gPROMS Olefins suite of Operational Excellence Solutions (OES) implements high-fidelity models online for coke monitoring, real-time yield reporting, run length prediction and furnace section optimisation.

Intermediates & Derivatives

PSE has world-leading technology for optimising reactor design and operation in the context of whole-plant optimisation. In addition, high-fidelity models can be implemented online as part of the gPROMS Reactor OES to monitor KPIs (including catalyst deactivation), provide soft-sensed values and optimise operation.


We provide industry-leading capabilities for optimising LPDE production, based on high-fidelity population balance models – coupled with CFD models where necessary – to provide accurate molecular weight distribution (MWD).

R&D laboratory facilities

PSE’s high-fidelity modelling approach integrates multi-scale first-principles models of physics and chemistry with experimental data for real-world validation. We can supply cost-effective laboratory experimentation capabilities, including design and execution of experiments.

Many other specific applications

PSE tools provide advanced process modelling capabilities for many key Chemicals & Petrochemicals process operations. Some examples are:

Advanced catalytic reactor design

Advanced reaction modelling technology makes it possible to design detailed reactors and include these in whole-plant flowsheet optimisations.
This means that you can optimise process designs taking all relevant interactions into account.

State-of-the-art separation models

ProcessBuilder provides state-of-the-art capabilities for steady-state and dynamic equilibrium distillation, rate based separation, pressure-swing adsorption, membrane separation and hybrid separation.

Solution crystallization

PSE provides unique capabilities for design, scale-up and operational optimisation of batch and continuous crystallization processes, including recipe optimisation.

Solids process modelling

PSE's unique capabilities for batch, continuous and semi-batch solids process operations use high-fidelity rigorous models to optimise design and operations.

Cyclic separation processes

The power of the gPROMS environment allows easy solution of complex complex separation processes such as pressure-swing adsorption.

Water treatment

Our extensive libraries of high-fidelity biological and physico-chemical wastewater treatment process models allow optimisation of design and operations as well as troubleshooting of treatment plants.
